Hopefully my code for these projects will be as good as it gets now, it has been working in 4 other projects with no trouble as it was, warts and all, but with decent power supplies.

Its all a learning curve, for instance it was only when I looked at a photo I took to post here of the UUT running, that I saw my celphone on charge 200mm away, I have been caught out with that before !

This unit will be fitted to a scoreboard on the far side of a field, so I don't have to worry about any interference from garage openers or celphones, but I couldn't take a chance. This should have gone out last week....

By next week I should be working on one project at a time, --- bliss

45 years of editing projects with a knife and soldering iron, then I found Arduino !
